Next.js vs Mithril.js: Which One Should You Choose?

In the ever-evolving JavaScript ecosystem, choosing the right framework can be a challenge. Next.js, a React-based framework, is widely used for server-side rendering (SSR), static site generation (SSG), and SEO-friendly web applications. On the other hand, Mithril.js is a lightweight JavaScript library designed for fast and minimalistic single-page applications (SPAs).

So, how do they compare? Let’s break down their features, performance, and best use cases to help you decide.

What is Next.js?

Next.js, developed by Vercel, is a powerful React framework that enables SSR, SSG, and hybrid rendering for modern web applications. It is known for its SEO-friendliness, fast performance, and scalability.

Key Features of Next.js:

Hybrid Rendering – Supports SSR, SSG, ISR, and CSR.
API Routes – Allows backend functionality within the frontend.
SEO-Optimized – Pre-renders pages for better search rankings.
Automatic Code Splitting – Loads only necessary JavaScript.
Edge Functions & Middleware – Enhances security and speed.

When to Use Next.js?

✔️ You need an SEO-friendly, high-performance web app.
✔️ Your project involves dynamic content, APIs, and server-side logic.
✔️ You prefer React and a production-ready solution.

What is Mithril.js?

Mithril.js is a modern client-side JavaScript framework for building SPAs. It is incredibly lightweight (only ~8KB gzipped) and focuses on performance and simplicity.

Key Features of Mithril.js:

Lightweight & Fast – Only 8KB in size, faster than React.
Virtual DOM – Ensures efficient rendering with minimal updates.
Simple API – Easy-to-learn routing and state management.
No Dependencies – Unlike React, it doesn’t require external libraries.
Performance-Optimized – Faster than most mainstream frameworks.

When to Use Mithril.js?

✔️ You need a lightweight, fast, and dependency-free SPA.
✔️ Your project is focused on performance and minimalism.
✔️ You want an easy-to-learn framework without a steep learning curve.
